Too embarrassed to tell his pals he failed his driving test, Les (Corey Haim) decides to throw caution to the wind (as 16 year olds are apt to do) and go on with his weekend plans. Not only do his friends, including crazy Dean (Corey Feldman), expect him to transport them around, but he has a date with his dream girl (Heather Graham) and nothing is going to stop him from meeting her. He steals his grandfather's 1972 Cadillac and promises himself that he will get it back without his parent's knowledge. But nothing goes according to plan, and Les is suddenly involved in a nightmare of an evening!
